15 Most Insanely Overpowered Superheroes In The Marvel Universe
11. Impossible Man
You may not be aware of this Poppupian alien from the planet Poppup (a not at all auspicious day in the Marvel creative office that one), but he's a big deal, no matter how silly he is.
He's a shape-shifter, like all of his species, and his power is so ridiculously amplified that he can take literally any form via molecular rearrangement. That means he can mimic every single Marvel hero, no matter how powerful and take on their abilities: he's essentially a swiss army character with no limits, and while he's no more than a comedic figure, if he ever took it upon himself to be a villain he'd be unstoppable.
On top of that unfeasible power, he's also capable of immediate inter-stellar and inter-dimensional travel, and matches his ability to mimic heroes with an encyclopedic knowledge of Earth culture. Which essentially makes him a hugely powerful cosplay nerd.
